Dating glacier layers the dating song

Ecofeminism and ecopsychology are mentioned, for example, as are terms from organic gardening and permaculture.

Because the life sciences messily overlap (that's life), terms from botany, biology, geology, chemistry, meteorology, and agriculture are included as well.

"These are relict stories, and piecing them together with radiocarbon dating and stratigraphic work would help piece together the chapters of the story," Connor said.

The researchers have not yet published the results from the investigation but plan to do so once they have gathered more data.

Laura has a good eye for finding fossils in unlikely places, will pull over to examine sedimentary layers in highway roadcuts, and has gone swimming in the Arctic Ocean.

The glossary that follows assumes a definition of ecology--the study of interactions between organisms and their environment--much wider than what fits under the field's habitual statistical persona.

Most of it is generated by sulfur dioxide and nitrogen dioxide (air pollution). Results include fish and plant deaths, corrosion, groundwater pollution, and soil erosion. Actinomycetes: formerly classified as fungi because of their filaments, the actinomycetales include many types of soil bacteria.

Anchorage, the state's most populated city, relies entirely on the retreating Eklutna Glacier for its drinking water.

Still, glacial retreat does offer an interesting opportunity to investigate well-preserved remnants of an ancient world.

"Mostly, people find chunks of wood helter-skelter, but to see these intact upright is kind of cool." The team has tentatively identified the trees as either spruce or hemlock, based on the diameter of the trunks and because these are the types of trees growing in the region today, Connor said, but the researchers still need to further assess the samples to verify the tree type.

A protective tomb of gravel likely encased the trees more than 1,000 years ago, when the glacier was advancing, Connor said, basing the date on radiocarbon ages of the newly revealed wood.

This year's summer retreat has not yet been calculated, but the team expects it to be relatively high due to unusually warm summer temperatures, Connor said.
